Product Description

The High-Back Mesh Ergonomic Office Chair with Headrest, model EMH-GRY-01, presents a professional task-seating solution in grey and black with a polished aluminum base. Its high-back form combines a breathable grey mesh backrest, matching grey headrest, woven grey fabric seat, and black polymer armrests, creating a structured appearance suited to modern office settings. The five-star base and twin-wheel swivel casters support a mobile, centered layout at desks or workstations. Construction balances flexible support with durable components. The backrest uses grey flexible mesh stretched over a black polymer and metal-tube perimeter frame, while the seat is formed with grey woven fabric over a contoured molded foam cushion and hidden load-bearing shell. The finished seat cushion is 90 mm thick, with 80 mm foam at a 45 kg/m3 density, and the backrest padding is 70 mm thick. A 240 mm lumbar support zone targets the lower back. The headrest is a padded fabric cushion on a black height-adjustable support. Arm pads and posts are molded in black polymer, and the base is polished die-cast aluminum with curved load-bearing legs. A chrome-plated steel Class 3 gas column provides a 100 mm stroke, paired with black nylon twin-wheel swivel casters. Overall dimensions are 670 x 670 x 1280 mm, with 540 mm clear width between armrests. The chair has a recommended user weight capacity of 135 kg and a net weight of 17.5 kg. Functional adjustment is designed for extended desk work. A pneumatic lever sets seat height from 450 to 550 mm. The synchronized tilt mechanism lets the backrest recline through 15 degrees, includes tension control, and can lock in the upright position. The separate headrest offers 80 mm of height adjustment and a 20-degree pivot for neck support. Armrest height changes through 60 mm of vertical travel using the visible side release button on each post. This chair is appropriate for open-plan offices, home offices, and workstation areas where lumbar support, swivel access, and seat-height adjustment are needed. It suits users weighing up to 135 kg who require seating for six to eight hours of daily desk work in carpeted or hard-floor environments. Procurement planning should note that each set ships unbranded in two cartons, with packaged gross weight of 23 kg and carton volume of 0.26 m3. Reference carton dimensions are 850 x 420 x 720 mm, assembly time is 40 minutes per set, and a 20GP container can accommodate 135 sets at 85 percent space utilization.
